  • The spectra are extracted from 3-6 arcmin annulus, centered on the cluster center
  • The scripts use a 1-temperature phabs x mekal model.
  • The column density is from Kalberla et al. (2005) and the absorption cross-sections are from  Balucinska-Church & McCammon (1992).
  • The scripts use the metal abundance table from Grevesse & Sauval (1998).



                               INDIVIDUAL FITS

                (Each cluster and instrument fitted separately, see Table A.1 in Kettula et al., 2013)

Triangulum      Suzaku/XIS0       Suzaku/XIS1      Suzaku/XIS3   



The script files xisX_Y_3_6_am_circ_newcal_Z_mekalfit.xcm will set up the best fit. In more detail:

  • "X" refers to XIS unit (0,1, or 3)
  • "Y" is the cluster name
  • "Z" refers to the band used in the fit (0520 = 0.5-2.0 keV;  2070 = 2.0-7.0 keV





                                    JOINT FIT

                (For each cluster all XIS instruments fitted simultaneously, allowing Oxygen column density of the contaminant to vary, see Tables 5 and 6 in Kettula et al., 2013)
